Application filed July 9, 1910. Serial No. 571,152.

To all whom it may concern:

Be it known that I, LUIs RivAs IRUZ, a citizen of the United MexicanStates, residing at Mexico city, Federal District, Mexico, have inventedcertain new and useful Improvements in Carbid-Holders for Acetylone-GasGenerators, of which the following is a specification.

This invention relates to carbid-hoppers for acetylene gas generators,in which a cup shaped valve member is held in the valve seat or mouth ofthe tapered carbid-hopper by means of a spring, and by providing on athreaded valve stem a check-nut on one side of the valve member andanother nut on the opposite side. The tension of the spring for keepingthe valve set is thereby made adjustable.

In the accompanying drawing, Figure 1 is a vertical section of thehopper, Fig. 2 is a top view of the same, Fig. 3 is a plan view of theremovable cover as well as showing the same in a side view and Fig. 4 isa vertical section taken on the line 1-1 of Fig. 1.

Referring to the drawing, the hopper proper is designated as (l) and isof the customary inclined tapered form at its bottom, where it isprovided with the discharge orifice (2) that forms the valve seat intowhich the inverted cup-shaped valve (3) is normally set, whereby thecarbid is obstructed from sliding into the water receptacle on top ofwhich the hopper is placed. Inside the hopper is disposed the transverseupper tubular support (4:) and thereunder the lower tube (5) both beingunited by the vertical tube (6) which lower end is inserted into thelower tube (5) and its upper end runs through the transverse uppert-ubular support The vertical tube .6 at fords a housing for thevalve-stem 7, and its pressure spring 10. By being jointed to thetubular supports 4 and 5, as indicated at 4: and 5, respectively, astrong and durable structure is provided, which will adequatelywithstand the strains of a large quantity of carbid around the tube 6,and the lower end of the vertical member 6 is not only substantiallysupported, but an inclosed action is provided for the lower end of thespring 10 and the washer 16. Furthermore, the lower end of the tube 6 isadequately sup ported, without obstruction of the carbid contained inthe hopper, since the rounded nature of the cross tube or support 5offers no crevice or ledge on which the carbid lumps can lodge, evenaround the joint formed by its juncture with the vertical tube 6. Thesame remarks apply to the upper transverse support 4:, no ledge beingformed around the member 6 or on the support proper to receive and holdthe carbid particles.

To the upper extremity of the valve stem (7) is rigidly fixed thepressing disk (8), and the collar (9) at some distance from the disk,fixed to the valve stem, guides this latter in its sliding movement upand down inside the vertical tube (6) under the action of a spring (10)that surrounds the stem and abuts against the collar (9) in its upwardexpansion, while the lower end of the spring, which is attached to thewasher (1G), rests upon the inner wall of the lower transverse tubularsupport (5). The other end of the valve stem that penetrates thetransverse tubular support (5) is threaded, and upon this extension isscrewed the checknut (11) so that'the inverted cup-shaped valve member(3) may be stopped at the desired distance when slipped on to the stemand afterward retained by the nut (12). By means of these two nuts (11)and (12) the tension of the spring may readily be adjusted in accordancewith the Weight of the bell, that floats around the hopper in the classof generators where the carbid is dropped into the water receptacle fromtime to time.

The mouth of the hopper is partly closed by the stationary half-cover(13) and the removable other half portion (14:) which is clearlydisclosed in the Fig. 3, excludes dampness and vapor from the interiorof the hopper. The hopper can readily be supported on the top of thewater receptacle of the gas generator by the lugs (15) projecting fromthe outside of the hopper,engaging the rim of the receptacle.

What I claim is:

1. In an acetylene gas generator, the co1nbination with a hopper havinga discharge bottom, a valve controlling said bottom and having a valvestem extending vertically in said hopper, a tubular housing inclosingsaid valve stem, a transverse tubular supporting element extendingacross said hopper at the lower end of said housing and jointed to saidlower end in a V-shaped joint to communicate therewith, and an uppertransverse supporting elementjointed to said housing to surround thelatter with a circular joint, said transverse elements acting to wardoff particles of carbid against lodgment.

2. In an acetylene gas generator, the combination with a hopper having adischarge bottom, a valve controlling said bottom and having a valvestem extending vertically in said hopper, a tubular housing inclosingsaid valve stem and depending centrally in said hopper, and upper andlower transverse elements extending to and supporting said housing, saidtransverse supporting elenients having curved surfaces adapted to wardoff particles of carbid against lodgment and the lower of saidsupporting elements having a V-shaped opening in its upper side to whichthe lower end of said housing conforms and is jointed.

In testimony whereof, I have affixed my signature, in presence of twowitnesses.
